Sobre la Estadística Win Shares


( Para la Versión en Español: Ver a Continuación de la Imagen! )

"One of the hardest things about assessing Basketball players is disentangling the effects of the different players on the floor. If a player gets an offensive rebound and the putback, how much should we credit the guy who drove to the basket, broke down the defense, and missed the shot, but put the defense out of position for the rebound?

When someone scores, how much credit should he get, how much should go to the guy who got him the ball, how much to the guy who set the screen, how much to the perimeter shooter whose defender was hesitant to come over and help, etc., etc.? When the shot clock winds down and someone who can create his own shot is forced to put up a tough shot, how do you spread blame among the teammates who were unable to create a good shot during that possession?...."

"...In other words, it's not clear how reliable the Win Shares statistic is at the kinds of interesting uses that Gladwell wants to put it to - assessing potential MVPs, comparing teammates, identifying overrated and underrated players, and so on. I think that it's necessary to keep track of plus/minus data, like WinVal does, in order to disentangle teammates......" Posted by "blar" at gladwell.com

The eBA Basketball Statistics Analysis System give answer to this questions in the chapter "eBA System Non Standard Statistics" which will be analyzed in the next exposition at eBAClinics.com, on December 26th. ª 21:00 GMT

By looking at LeBron’s final four seasons in Cleveland and his previous four seasons in Miami, we can compare his impact across the same number of seasons on each team. It is clear to see that his win share total in each season accounts for roughly 30% of his team’s wins. He had a greater impact in Cleveland, which makes sense considering the talent differences between there and Miami.

"Uno de los elementos más difíciles en la evaluación de un jugador reside en la determinación de los efectos de los diferentes jugadores en el campo. Si un jugador logra un rebote ofensivo y palmea para la conversión, cómo acreditaremos nosotros al jugador que se mandó al aro, quebró la defensa, y erró el lanzamiento, pero puso a la defensa fuera de posición para el rebote ?

Cuando alguien convierte, cuánto crédito él recibe, cuánto debe ser acreditado al quien le pasó el balón, cuánto a quien estableció la cortina, cuánto al lanzador desde el perímetro cuyo defensor estuvo dudando si abandonarlo y venir a ayudar, etc., etc. ? Cuando el reloj se está agotando y alguien que puede crear su propio lanzamiento se ve forzado a lanzar un tiro difícil, cómo se reparte la responsabilidad entre los compañeros que fueron incapaces de crear un buen lanzamiento durante esa posesión ?...."

"...En otras palabras, no está claro cuan confiable es la estadística Win Shares en el área de interés a los que se refiere Gladwell - evaluando MVP potenciales, comparando compañeros, identificando jugadores sobre-evaluados y minusvalorados, y así en más. Yo pienso que se debe llevar un registro de los datos de la valuación plus/minus, como lo hace el WinVal, a efectos de comparar y diferenciar compañeros de equipo......"
